Application filed November 28, 1913. Serial No. 803,568.

instance such bowl provides for the sepa rate reception of solid and liquid excrement, which renders it of particular value when it is desired to make an examination thereof, as in cases of use by the sick.

My improved bowl is particularly available for hospital use, although it is adapted for general use as well, and when employed for ordinary house use its construction, which makes it peculiarly desirable for hospital use, is of very great value.

These and other features of my invention are more particularly described hereinafter, reference being had to the accompanying drawings, in which:

Figure 1, is a longitudinal sectional elevation of a closet made in accordance with my invention, taken on the line 11, Fig. 2; Fig. 9., is a plan view of same; Fig. 3, is

aview similar to Fig.1, showing a modifi cation within the scope of my invention; Fig. 4, is a vertical sectional view, taken on the line 4'l, Figs. 1 and 3; Fig. 5, is a sectional plan view, taken on the line -5-5, Figs. 1 and 3; Fig. 6, is sectional elevation similar to Figs. 1 and 3, showing a further modification within the scope of my inventicn, taken on the line 66, Fig. 7, and Fig. 7, is a plan view of the structure shown in Fig. 6.

In the drawings, 1 represents the bowl of my improved structure, having the usual flushing rim 2, provided with outlets 3, and with a special enlarged and elongated jet outlet 4, at the front of the bowl. The bowl is provided with a pan or receptacle 6, of the type common to wash-out water closet bowls, and the opening or outlet 4: at the front of the bowl is arranged to discharge a jet of water in a curved path; following the surface of the front of the bowl and said pan or receptacle 6. The contents of the pan or receptacle 6 overflow into a well 0 Outlet passage 7 which communicates directly with the ascendinglegS of a'siphon conduit the descending leg of which siphon conduit is shown at 9. The construction of this siphon'conduit is such that a deep seal is provided, and the bowl provides separate receptacles for the solid and liquid material deposited therein. The descending leg or passage 9 of the siphonconduit is provided with projections 10, 11 and 12,-and with a contracted portion 13 between the projections 10 and 11, in accordance with the coinmon practice of constructing closets of this character for the purpose of inducing siphonic action. Between the projections 10 and 12, a deflecting surfacell is provided to aid siphonic action.

The flushing water is introduced into the bowl through a spud 15 at the rear of the bowl; a portion passing to the flushing rim 2, while another-portion is delivered to a jet passage 16, whichmay. discharge at '17 into the well or outlet passage 7 leading from the bowl to the up-leg of the siphon conduit; the purpose or function of which et passage is to provide-a stream of water of driving value to move the body of water in the seal in advance of the motion that would be imparted thereto due to the mass of Water passing fro-m the flushing rim and discharging into the pan or receptacle6 in the upper portion of the same, and overflowing from the latter to the outlet pas: sage 7. At the same time, the pan 6 is secured clean by the stream of water emerg ing from openings 3 and the jet opening 4: at the front of the bowl; the latter having greater force. 7

As constructed. the pan 6 will receivethe liquid portion. while the well 7 will receive the solid portion of excrement deposited in the bowl. The rear jet passage 16 may receive approximately one-half of the flushing water, so that a considerable amount of force will be imparted to the jet of water issuing from. the outlet 17 thereof, and this jet engaging the water in the seal. will move the latter quickly, overflowing the dam 18 and insuring prompt siphonic action.

The dam may be constructed in any suitable manner, but'in the drawings, I have shown the same as rounded or concaved.

I do not wish to be limited to the use of a jet discharging from a point above the seal into the water thereof, as shown in' Fi s. 1 and 6. since I may employ a jet F ig. 3, which extends Well below the seal and is provided with an outlet l7 turned or curved so as to dischargetoward: thedam to effect a pushing action upon the water in front ofit; thereby enabling the water behind it to quickly enter the siphon ct'ind'uit; from t lie out-l'e't' passage or Well 7.

The form of bowl illustrated, in; FigsyG: and 7, is provided With an, extension lip 19,, and; the fmnt; jet; illustrated? at 4:3" in I Fig; 6,1 is, formed ini the same in a. manner: like-that; showniin Figs.- 1 and 3.
